My invention relates generally to apparatus employing a receptacle in which suction is exerted to draw into it liquid, as for example oil, and more particularly to appa- Vratus provided for the evacuating of oil cas- 4 ings of automobiles, and especially the crank cases thereof, and discharge of the same into the receptacle in which the suction is created, preliminary to the re-lling of the crank case with fresh oil.

Certain of my objects are to provide bysimple and economical means, for the ready and veffective cleansing of the receiver of such deposits as may accumulate on the inner surfaces thereof, and which itis desired be kept clean especially to permit of the observation of the contents of the receiver when the side wall is made of glass; and to provide, by a unitary structure, for the discharge of the cleansing fluid against different portions of the inner surfaces of the receiver, as desired, and for the desired downward projection of the -oil evacuated from the container to be em tied.

eferring to the accompanying drawings, in which I have illustrated my invention as incorporated in an apparatus for receiving the used oil from crankcases of automobiles, and of the general type disclosed in my Dending applications for U. S. Letters Patent Serial No. 13,819, filed March 7, 1925, and Serial No. 32,745, filed May 25, 1925, and linvolving a fluid-pressure-operated ejector-'device for exerting suction in the receiver for drawing the oilinto the latter from the crank case, the suction producing means being in the form of a fluid-pressnre-operated` ejec-v tor-device Figure 1 is a view in elevation ofan evac uatingI apparatus of the type referred to and in which my present improvements are incorporated, the liquidconduit of the apparat-us being shown as extending into a tank of cleansing fluid for supplying such fluid for the cleansing purpose.

In explanationof the illustrated apparatus, as regards those features forming the subjects of my said applications, it may be stated that 10 represents a receiver for receiving the used oil from the crank cases 'of automobiles, the side wall 1-1 of this receiver being constructed of glass to permit of the observation of the oil drawn into it. The receiver 10 is provided in its top with a fluid-pressure-operated ejector-device 12 supplied with compressed air from any suitable source throughv pressed air discharging upwardly through the pipe 13 and through the ejector device 12 and out ythrough the exhause pipe 15 creates suction at the openings 14, in the receiver 10.

The pipe 13 is surrounded by a pipe 16 spaced y therefrom and communicating at its upper end with the upper part of the receiver 1() and at its lower end, by a passage 17 in the bottom of the receiver 10, with apipe 18 which leads to a. iiexible hose line 19 equipped with,a rigid extension-pipe device 20 having at its inlet end, a fitting 20% asfor example as shown in the drawings andas set forth in said application Serial No.' 32,745, to facilitate its connection with the lower drain openings of crank cases to'be evacuated'of their oil content, and to which the suction created in the receiver 10 is supplied through the pipe 16, passage 17, vpip-el 18 and hose-lineA 19 to transfer the oil in the crank case to the.

of compressed air for supplying the pipe 13 with the ejector-operating pressure.

The ejector-device 12 is formed of a hol- I low head 25 located in an opening in the top of the receptacle 10 and into the lower end of which the pipes 13 and 16 are threaded, theportion of the head 25 above the upper l open end of the pipe 16 containing a chamber `26- the side wall of which contains radial equidistantly spaced laterally-opening outlets 27, shown as six in number, and` forming the outlet for the tacle 11.

Assuming air under pressure to be supplied to pipe24 and the valve in the extension pipe to be open, air under pressure is supplied pipe-16 into `the recepto the ejector-device which, in'reducing thev air pressure in the receptacle 10, exerts suction on the inletof the extension pipe 20 for drawing liquid with which it is in communication, as for example liquid in a cra-nk case from the drain opening to which the extension pipe is applied, linto 'the receptacle l() through the openings 27.

In accordance with the preferred illustrated embodiment of' my invention,-,I provide for the supplying of cleansing liquid to the inner surfaces of the receptacle 11 through Y. the extensionpipe 2O and pipe 19, under the Suction action produced by the ejector-device 12, the inlet end of the extension pipe 20 in such use of the apparatus being positioned in a tank, as for example that shown at 100, of the cleansing fluid which is drawn into and through the extension pipe and pipe 19 and thence into the receptacle'10.

The means shown for controlling thedisl charge of the cleansing fluid into the receptacle 1 0 and which, in the particular embodiment of my invention, are unitary with means for deflect-ing the yusedoil discharged into the receptacle 10, comprise a sleeve 28 surrounding the lower portion of the head 25 and slidable vertically thereon, the sleeve 28 Acontaining aseries of radial eqidistantly spacedopenings 29 shown1 as ysubstantially horizontally disposed, and having its inner upper per1pheral edge slightly rounded, as represented at`30. The lower end of the sleeve 28 is provided with a skirt portion 3l' annularly spaced from the portion of the head which it surrounds, with its lower edge slightly inwardly deflected as represented at 32. The sleeve 28 is provided with outwardly projecting pins 33 to which are pivotally connected the arms 34 of a yoke 35 secured to the upper end of a rod 36 which projects downwardly through a stuffing-box 37 in the bottom of the receptacle 10, the lower end of this rod carrying a head 38 containing a transverse slot 39 in which one end of a lever 40 pivoted on a pin 41 onthe standard '21, extends, whereby upon actuating the lever 40 the sleeve 28 is raised or .lowered depending upon the direction in which this lever is rocked.

In the use of the apparatus for vdisplacing fluid, as forexample oil from the crank case, the sleeve 28 occupies the position shown in Fig. 4 and the fluid in discharging from the head 25 into the receptacle 10 is deflected downwardly by the skirt portion 31.

In the use of the device for cleansing the interior of the receptacle 10, the operator rocks the lever 40 to shift the sleeve'28 downwardly to the position desired, as for example to the position shown in Fig. 7 or that shown in Fig. 8. When the sleeve is lowered to the position shown in Fig. 8the openings 27 are partially uncovered at their upper edges and thus the cleansing fluid, sucked for example from the tank 100 through the liquid-pipes described and as stated, clischarges forcibly in an upwardly inclined direction against the underside -of the top of the receptacle and as the sleeve is moved down from this position the streams of` cleansing fluid become progressively less inclined impinging against the inner surface of the receptacle farther and -farther'from the center thereof, the discharge of the fluid as described reaching those inner upper portions of the receptacle which would not be impinged by horizontal streams. Following this operation the operator raises the sleeve 28 to',the position shown in Fig. 7 in which the openings 29 register with the openings 27 landthe cleansing-fluid discharges forcibly in a substantially horizontal direction against the side wall of the receptacle 10 to complete the cleansing of the walls of the latter. Following this operation the operator further raises the sleeve 28 to a position in which the interior of the skirt 31 registers with the outlets 27 whereupon the cleansing fluid discharges downwardly along lthe pipel 16 cleansing the latter of accumulations.

The head 25 is preferably provided as shown, with an annular laterally-extending flange 42 above the sleeve 28, this flange serving to outwardly deflect the cleansing fluid and minimize drawing of the fluid into the suction openings 14 when the sleeve is adjusted to the position shown in Fig. 8.

The Cleansing fluid may be removed from .the receptacle by opening the valve 43 which controls a waste pipe 44 opening into the bottom of the receptacle 10.

It Will be understood from the foregoing that by constructing an apparatus in accordance 'with my invention the cleansing operation may be performed with great facility land that the mechanism provided for producing the cleansing operation is ofv simple and economical construction.

While I have illustrated and described a particular embodiment' of my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.
